But when I was researching this same thing a year ago, I had taken a hard look at the Lunati retro hydraulic roller lifters. They're designed to be compatible w/higher than normal spring pressure that's usually needed for elevated rpm use, so you might want to start there. Using the lightest possible valve train components will also help in general.

Good luck.

alright, thanks yeah I believe those lifters are around 700 bucks. But if its wroth it I guess why not spend it... ill check them out thanks for the info

Good luck.

why dont you use solid rollers if you want to rev that high? use shafts also?

The reason i didn't really go with solid roller, I just didnt want to go thur the trouble of trying to adjust the valves and the headache especially for my first engine build so my engine builder told me to stay with HYD roller. Maybe on my next engine build I probably might go soild roller....
